Packing material

N0 Drawing.

paratus and appliances for handling and, delivering oils, particularly hydrocarbons.

Heretofore various forms of packing material have been used for oil pumps and pipe fittings and joints, valves, etc., used in pipe lines "for handling oils, a common form being rubberized fibrous material. It has been found, however that such packings rapidly deteriorate and have a tendency toward deformation resulting in the'loss of the tightness of the joint or seal, as a result of continued contact of the oil there- I with. I

Packing material made in accordance with my invention is adapted for use in relation where it is constantly subjected to the action oil-oils, either gasoleneor other hydrocarbon oils, without likelihood of swelling,

softening or becoming disintegrated.

To secure packing material having the desired properties, I employ a mass of loose, absorbent fibers, such as cotton sliver, in

which is incorporated a viscous or sem1- viscous material insoluble in oils of the character coming in contact with the packing. This material is used in sufficient volume to insure a thorough saturation or impregnation of the mass of fiber and'the presence of a superficial coating upon the separate fibers s'uflicient to form a bond therebetween and make the mass impermeable to the oils. The base of this material may be shellac, glue or other similar material capable of beingireduced to the desired viscous state and of -being absorbed by the fibrous mass. v a

In practice, I have secured highly satisfactory results by means of packing mate Specification of Letters Patent.

rial formed of cotton sliver saturated cr impregnated with orange shellac dissolved in methyl alcohol, sufficient gy'lcerin added to prevent the hardening oil the min"- ture and preserve flexibility therein and pliability m the packing mater sliver, after being thoroughly saturated or impregnated with this mixture, may be twisted in strands of the desired thin ne and configuration. This viscous or viscous material not only forms a any cial coating upon the fibers, forming a between adjoining fibers, but serves filler between the fibers, thus not only tecting the fibers from the deleteri tion of oil therein, but making the wh le 61?; mass impermeable to such oils.

Other fibrous materials may be used in lieu of cotton, and oil resisting material, and unctuous materials to prevent harden ing of the mixture, other than those specified may be employed. 1

Packing material made in accordance with my invention has been found to resist the action or oils particularly gasolene,

all'joints sufiiciently tight to prevent lea at age of the oils. Such a packing does disintegrate with continued use, does not swell or soften, and does not lose its form,

Having described the invention what It claim as new and desire to have protected by Letters Patent is {a 1. Packing, material comprising fibr shellac dissolved in alcohol and contain... an unctuous material.

2. Packing material comprising a mass ct loose fibers, saturated or impregnated with. orange shellac dissolved in methyl alcohol 3. A. packing consisting of a mass elf fibers coated and united by an oil l'QSlS Lttllt and flexible resinous composition including a non-drying agent.
